Preheat the oven to 425 degrees F. Grease or line a baking sheet with parchment paper.
In a small bowl, mix the peanut butter, peanuts, bacon and bananas until combined.
Divide the pizza dough into 4 equal balls and roll each into an 8-inch circle. Scoop one-quarter of the banana mixture onto half of each piece of dough. Top each with 1/4 cup of the dulce de leche. Fold the dough over the filling, stretching to fit, then align the edges and seal with egg wash. Press the edges with a fork to seal. Place the hand pies on the prepared baking sheet. Brush the tops with egg wash and cut 2 slits in the top with a sharp knife. Sprinkle each with 1 teaspoon of the turbinado sugar. Bake until golden brown, 20 minutes.
